PRELIMINARY
ML6430/ML6431*
Genlocking Sync Generator with
Digital Audio Clock for NTSC, PAL & VGA
GENERAL DESCRIPTION
The ML6430/ML6431 are multi-standard single-chip
BiCMOS video Genlock ICs for NTSC, PAL and VGA.
They are designed to provide a stable clock from an
analog video signal, and to provide timing pulses for
clamping, decoding, blanking and processing video
signals. The ML6430/ML6431 handle VCR glitches and
variations created by head switching, tape dropouts,
missing sync pulses, freeze frames, high speed playback
and camcorder gyro errors. The ML6430/ML6431 are
designed for high noise immunity, insensitivity to varying
signal amplitudes, overmodulated color carriers, and sync
glitches. Advanced analog and digital clock synthesis
techniques provide multi-standard and non-standard
operation from a single crystal or external asynchronous
clock source. Pin selectable preset modes allow operation
for most video standards in simple stand-alone mode
without the necessity of using the serial bus. For more
demanding applications, a two wire serial control bus is
available for full control of all of the ML6430/ML6431
features.
The ML6430/ML6431 are ideal for clock generation in
MPEG encoders, high performance display timing, and
video editing.
